ChangeLog
どうも，土曜日の更新が少ないような気がして調べてみた．
ちなみに，chalow からソースぱくりまくり．
#!/usr/bin/env perl
use strict;
use Time::Local;
my $fname = shift;
open(F, $fname) || die "file open error $fname : $!";
binmode(F);
my %day;
while (<F>) {
if (/^(\d{4}-\d\d-\d\d)/) {
eval { $day{get_day_of_week($1)}++; };
}
}
close F;
my @week = qw(Sun Mon Tue Wed Thu Fri Sat);
foreach (@week) {
printf "%s (%d) %s\n", $_, $day{$_}, '*' x $day{$_};
}
sub get_day_of_week {
my ($d, $m, $y) = @_;
($y, $m, $d) = split("-", $d) unless (defined $m);
my $WEEKDAY = (localtime timelocal(0, 0, 0, $d, $m - 1, $y))[6];
return qw(Sun Mon Tue Wed Thu Fri Sat)[$WEEKDAY];
}
- 結果: 予想通り
Sun (48) ************************************************
Mon (72) ************************************************************************
Tue (64) ****************************************************************
Wed (69) *********************************************************************
Thu (68) ********************************************************************
